IMPROVEMENT IN CLIP KING-BOLTS.

Specification forming part of Letters Patent No. 221, 184, datedNovember 4, 189; application filed September 20, 187 9.

.To all whom it may concern:

readily on the bolt, the two being made separately, and also to preventbreakage at the shoulder formed by the collar when under tension.

In the drawings, Figure lis a front view of the king-bolt set inposition on the T- plate and head-block. Fig. 2 is a transverse sectionof the same. Fig. 3 is a front view ot' the king-bolt, showing` the clipwith its collar or shoulder, the bolt proper, and the washer or nutbeneath the T-plate, which holds the bolt steady and prevents it fromturning while the clip revolves upon it. Fig. tis a front view of anordinary clip kingbolt. v

In the construction ot my improved clip king-bolt the clip A is forgedseparately from the bolt, and is provided at its base with a shoulder orcollar; and a round hole of two diameters, the upper one smaller thanthe lower, so as to form a' shoulder on the latter, is drilledverticallythrough-its center, in which the bolt revolves.

The bolt' B is formed with a conical-shaped head, which rests on theshoulder in the hole in the center of the clip. The portion of the boltbeneath the head must be round, the length only of the shoulder orocollar of the clip, and the thickness of the T-plate C, on which itrests, this portion of the bolt being round, in order that the clip mayrevolve or turn upon it.

The lower portion of the bolt, ,which is in closed within the head-blockD, must be triangular, square, or polygonal in shape, in order that itmay be fitted into the stationary washer or nut E, of correspondingshape, inserted in the head-block, and so be held firmly rigid, Whilethe clip revolves or turns.A upon the bolt around its upper rounded porpt-ion.

In fastening the bolt to the head-block, the carriage-builder will turna screw-thread on the end of the bolt which passes through and projectsbeyond the under side of the head block, and a nut is screwed upon thisend of the bolt to fasten the whole device` and hold y it in position. I

I deem it advantageous to place a leather washer on the shoulder formedby the round hole of large diameter in the center of the clip, toprevent the wear of the head of the bolt on the shoulder; and I alsoadd, for a similar. purpose, a leather washer in the hole of theT-plate, to prevent wear of the base of thc shoulder or collar of theclip, which rests upon and partly revolves within the T- plate.

I have shown in Fig. -1 of the drawings an ordinary clip king-bolt inorder, by comparison, to show more clearly the advantages of myimprovements.

With the ordinary clip king-bolt, of which the clip and the bolt areforged in one piece, there is a constant danger of the bolt breaking atthe shoulder formed by the collar when under tension.

With my improved clip king-bolt this is impossible, because there is notension or strain at this point, the clip and the bolt being madeseparately, and the former revolv5 ing upon the latter; and this is theprincipal feature of my improved clip king-bolt, because, in addition tothe advantage already mentioned, the bolt turns easily in the clipwithout binding or strain; and,furthermore,

the conical-shaped head of the bolt proper,

which sets in the axle-bed, keeps the clip from slipping, whichfrequently-occurs in the use of ordinary clip king-bolts.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is n A clip king-bolt for carriages and Wagons,consisting of the combination of the clip A, provided with a shoulder orcollar with a central hole or opening of two diameters, the

bolt B, having' a oonieal shaped head, and In witness whereof I havesigned my name' rounded at; its upper end, and square, trianto thisspecification in the presence of two gular, or polygonal at its lowerend7 and the subscribing wltnesses.
